[0031] The CNC grinding machine also includes a worktable 15, which is fixed to the middle of the support plate 12 and located on the side of the fixture 16;

[0032] The equipment base 10 provides support, the slide 11 can move the support plate 12 and the worktable 15, the support plate 12 and the support column 13 provide support, one end of the grinding mechanism 14 is connected to the lifting mechanism inside the support column 13, and the other end is equipped with a grinding wheel cover, with a grinding wheel rotatably connected inside for grinding products, the worktable 15 is used to fix products, the clamp 16 provides clamping function, and the tool 17 is used to grind and dress the grinding wheel.

[0033] The shielding assembly includes a fixing plate 20, a connecting shaft 21, a U-shaped protective cover 22, a first connecting block 23, and a second connecting block 24. One end of the fixing plate 20 is fixed to the side of the support plate 12, the connecting shaft 21 is fixed between the two fixing plates 20, the first connecting block 23 is sleeved in the middle of the connecting shaft 21, one end of the second connecting block 24 is fixed to the side of the first connecting block 23, and the lower end of the side of the U-shaped protective cover 22 is fixed to the other end of the second connecting block 24.

[0034] The first connecting block 23 is rotatably connected to the connecting shaft 21, and when it is close to the support plate 12, its upper end is higher than the support plate 12;

[0035] The U-shaped protective cover 22 is movably connected to the support plate 12 and the outside of the cutter 17;

[0036] The fixed plate 20 provides support, the connecting shaft 21 facilitates the rotation of the first connecting block 23, the first connecting block 23 and the second connecting block 24 provide connection, and the U-shaped protective cover 22 provides protection.

[0037] Working principle:

[0038] When installing the product to be polished, pull the U-shaped protective cover 22 to move the second connecting block 24, which in turn causes the first connecting block 23 to rotate around the connecting shaft 21 between the fixed plates 20, so that the U-shaped protective cover 22 covers the tool 17. After fixing the product to be polished, pull the U-shaped protective cover 22 open to expose the tool 17.

[0039] This step can shield the blade 17 to prevent it from scratching workers during product installation.

[0040] Please see Figures 3-4 This embodiment, based on the above embodiments, further includes:

[0041] The limiting component includes a first groove 30, a spring 31, a pull plate 32, and a baffle 33. The first groove 30 is formed at one end of the support plate 12 and is located on the side of the clamp 16. One end of the spring 31 is fixed inside the first groove 30. The side of the pull plate 32 is fixed to the other end of the spring 31. The baffle 33 is fixed on the other side of the pull plate 32 and is located inside the first groove 30.

[0042] The limiting component also includes a limiting plate 34 and a second groove 35. The limiting plate 34 is fixed to the upper end of the first groove 30, the second groove 35 is opened on the side of the first connecting block 23, and the baffle 33 is movably connected in the second groove 35.

[0043] The first groove 30 is used to install the baffle 33. The spring 31 has a telescopic function. The pull plate 32 facilitates hand operation of the baffle 33. The baffle 33 and the limiting plate 34 play a limiting role. The second groove 35 plays a connecting role.

[0044] Working principle:

[0045] Pulling the pull plate 32 causes the baffle 33 to move along the first groove 30 and below the limiting plate 34, compressing the spring 31 and moving the baffle 33 away from the first connecting block 23. At this time, the U-shaped protective cover 22 can be rotated. When the U-shaped protective cover 22 covers the cutter 17, the pull plate 32 is released, the spring 31 extends, and one end of the baffle 33 moves into the second groove 35. When the U-shaped protective cover 22 is opened, the baffle 33 is located above the first connecting block 23, which can prevent the first connecting block 23 from rotating.

[0046] This step prevents the U-shaped protective cover 22 from shaking when the slide 11 slides.
